A Mumbai-based firm's payment portal is flooded with millions of fake requests from many compromised computers, making it unavailable to genuine customers for several hours. Which security objective is most directly affected?
Availability is most directly affected. A flood of fake requests from many compromised machines is a distributed denial-of-service attack, which stops genuine customers from reaching the service. Nothing in the scenario suggests data was read or altered, so confidentiality and integrity are not the main concern.
- AConfidentiality
- BAvailabilityCorrect
- CAuthenticity of the sender
- DData minimisation
Explanation
A distributed flood of requests that makes a service unusable to genuine users is a DDoS attack. Its direct impact is on availability. No data was stated to be disclosed, so confidentiality is not the primary issue.
